D820 would be my first choice, I have one and it's the best phone I've ever owned. My second choice would be the German made 6270 but if you're willing to buy the 6270 why not spend $10 extra and get the new 6280 at easycell.ca. As for the W810i...don't make me laugh...for what it costs, it's so not worth it.
well that really depends on how you see it. some ppl like the ease of use of the sony phones. and the look is definitely better than a nokia phone any day. comparable with a d820? perhaps.. is d820 better.. i woudlnt' say so. but it really depends on your style right? what do you want more.. slider phone. candy bar phone.. ease of use and more functions.. or less functions and still ease of use. lots of things to consider
